Technical Diving opens up a whole new world to normal recreational diving. Go where few humans have ever been and have the chance to explore more wrecks, caverns and canyons and sea different types of aquatic life. Decompression diving also allows you to stay deeper more much longer periods letting you spend more time on each dive site.

PADI have recently introduced a range of 'TecRec' courses to allow you to work your way up (or should we say down?) the deep diving path:

Sidemount

Sidemount diving is one of the fastest growing areas in the diving arena. You'll free greater freedom, be more streamlined and it's kinder on the back too. It's also a great way to start off before your tec diving really kicks off.

The course takes 3 days and includes one confined water dive and 4 open water dives. You'll spend lots of time figuring out the best configuration for you, gas management, buoyancy control, shutdowns and gas sharing.

Tec 40

The PADI Tec 40 is your first step in to technical diving. You’ll dive in the full tec rig and practice the key tec skills to make you a safer technical diver. Our Instructor Alex makes this a course the foundation for all future tec courses. You can do this course in either backmount or sidemount.

The course takes 3 days and includes a day of theory and shallow water skills. On the final day you'll have a go at doing a deco dive and upon completion you'll be able to do a 10 minute deco dive at 40m using a stage of up to 50% O2.

Tec 45

The Tec 45 course is where it really gets interesting! Not only will you be qualified to dive to 45m by the end, but you'll also be able to do deco stops with up to 100% O2.

The course takes 3 days to to complete. The first day is a day of theory, equipment set up and a skill circuit dive. You'll learn about shut downs, gas sharing and gas switching. On the final day you'll do a qualifying deco dive. You can also combine sidemount with this course.

Tec 50

This is where Tec Diving gets serious! You'll be able to carry two stages enabling you to do important gas changes. You'll learn more about dive planning giving you extra confidence when in the water.

The course takes 3 days and includes some theory, a skill circuit, you'll learn about handling multiple stages and gas switching. You'll then do 2 decompression dives and have the option of using trimix on the final dive.

Tec 65

The Tec 65 course is all about trimix and managing your stages. You'll learn to handle 3-4 stages and plan trimix dives using O2 mixes of 16% and upwards.

The course takes 3 days to complete. You'll do some shallow water skills and learn how to handle multiple stages. You'll do a full trimix dive before qualifying. There are also options to complete the course abroad to take advantage of some deep wrecks.

Tec Trimix

This is the big one where you'll learn about hypoxic trimixes and travel gases to achieve the desired depth. Once qualified you'll be qualified to dive to 100m.

The course takes 4 days to complete but you might want to think about completing the course overseas where you can take advantage of clearer seas and amazing wrecks. The course includes the issues faced by divers planning hypoxic dives.
